Thanks for the link and info. My LBS is right across from work so I dropped it off. I bought a new saddle from them so they said they would check it out for free. I tried the oil on the spokes where they cross and that didnt help. May just need the spokes tensioned.
I am 200 lbs. I also did have someone listen as i rode...thats how i narrowed it down to something in he back.
Noises will drive you crazy....especially the ones in your head HAHA
